When using chassis clustering, which action is taken by the Junos OS if the control link or the fabric link suffers
a loss of keepalives or heartbeat messages?
A.
Both nodes become primary.
B.
Both nodes are placed in a disabled state.
C.
The secondary node is placed in a disabled state.
D.
The primary node fails over and is placed in a disabled state.
C
The system provides each fxp1 control link interface with an internal IP address and uses the proprietary Trivial Network Protocol (TNP) to transmit the session state, the configuration file, and liveliness signals across the nodes. The Junos OS periodically transmits heartbeat signals over the control link to determine the health of the control link. If the number of missed heartbeats reaches the configured threshold and the fabric link is operational, the system signals a control link failure. If the control link fails, the Junos OS disables the secondary node to prevent the possibility of each node becoming primary for all RGs, including RG0. Once a secondary node is disabled, you must reboot the node to resume operation
